Microbats injured in New South Wales and the ACT no longer need to go to Queensland for flight rehabilitation.

A new aviary has been built at Windellama near Goulburn allowing high-flying species to regain their flight fitness locally.

Bats which are injured or sick and taken into care can start to lose muscle and fitness in just two weeks.

"It takes intensive flight time to rebuild that fitness and finding safe places to fly some species had been difficult," said Heather Caulfield, bat coordinator for the Wildlife Information, Rescue and Education Service (WIRES).

Microbats which fly and hunt above the forest canopy have wings adapted for very fast straight flight and many need to drop from a height of four metres to gain velocity to take off.

"Some species like the freetails won't even attempt to fly unless they can echolocate a minimum of eight clear metres around them," Ms Caulfield said.
